On our 10.6.8 Mac Mini Late 2009 Edition, we have 4 users, 3 of which are in regular use. One is mine, let's call it 'a'. The second one is someone else's, let's call it 'b'. The third one we both use, let's call it 'c'. a and c have administrator rights. The unused is the owner.
So, the 'a' account is kind of slow sometimes, but it's what you'd expect after almost 5 years of usage. But here's the deal. 'b' and 'c' often behave much slower than that (takes 2-5 minutes to complete login). Sometimes they're as fast as 'a', but that's seldom.
So yeah, whaddya think about this? Why does this happen? And if you know why, how can I fix it?
